THOMAS A. EDISON PAPERS
A SELECTIVE MICROFILM EDITION
PART II
(1879-1886)

REEL 29

NOTEBOOK SERIES (NBK-7)

Menlo Park Notebooks, #1 - #10

NOTEBOOK SERIES, 1879-1886

Several sets of technical notes and drawings comprise the Notebook Series
for 1879-1886. They appear on the microfilm in the following order: (1) Menlo
Park Notebooks, (2) New York Notebooks, (3) Fort Myers Notebooks, (4) Lamp
Factory Notebooks, (5) Pocket Notebooks, (6) Technical Scrapbooks, (7) Unbound
Notes and Drawings, (8) Oversize Notes and Drawings, (9) Undated Notes and
Drawings. All of the bound notebooks, except for the technical scrapbooks and the
pocket notebooks are standard-size, 6 inch x 9 inch notebooks containing between
280 and 290 pages. Edison began using these notebooks in November 1878, and he
continued to use them throughout the remainder of his life.

(1) Menlo Park Notebooks, 1878-1882. These notebooks are the principal
sources for documenting the invention and development of Edison's system of
electric lighting and power. They also contain much material on the telephone, as
well as scattered entries detailing work on electric railways, batteries, ore
separation, telegraphy, and various other technologies. The entries in the early
notebooks are primarily by Edison, Charles Batchelor, and Francis Upton. As the
staff of the laboratory expanded, many other individuals began making entries in
the notebooks. A few of the books contain entries from 1883, 1884, and 1885. The
notebooks are numbered from 1 to 249. Approximately 70 books are missing from
the set.

(2) New_York Notebooks, 1884-1886. These ten notebooks were used at
Edison's New York City laboratory, which was located above the offices of
Bergmann & Company at Avenue B and 17th Street. Most of the notes, drawings,
and calculations are by Edison. There are also some entries by John F. Ott, Ezra T.
Gilliland, H. DeCoursey Hamilton, Montgomery Waddell, and other laboratory
assistants. The books deal with a wide variety of subjects, including electric
lighting and power, telephony, telegraphy, mining, and the phonograph. Several
books contain entries pertaining to Edison's search for a new force and his attempt
to convert heat directly into electricity.

(3) Fort Myers Notebooks, 1886. These seven notebooks were generated at
Edison's winter home in Fort Myers, Florida, which he constructed shortly before
his marriage to Mina Miller in February 1886. Most of the entries are by Edison.
There are also some entries by Mina Miller Edison, whose name also appears in
these books as a witness. Many of the notes and drawings concern phonoplex and
multiplex telegraphy, Edison's search for a new force, and his attempts to convert
heat directly into electricity. There is also material relating to electric lighting,
electric railways, spectroscopy, hearing aids, and numerous other items. One book
contains notes about the layout of the grounds at the Fort Myers home.

(4) Lamp Factory Notebooks, 1886. These seven notebooks contain notes,
drawings, and calculations relating to experiments performed at Edison's lamp
factory in Harrison, New Jersey. Most of the entries are by Edison and John F.
Ott. One book contains entries by Mina Edison. Another book was used primarily.
by Ezra T, Gilliland. In addition to the lamp experiments, these books also contain
notes and drawings pertaining to telephones and phonographs, along with some
material dealing with the phonoplex and with other systems of railway telegraphy.

(5) Pocket Notebooks, 1878-1886. These are a group of miscellaneous books,
generally measuring about 3 to 4 inches in width and 6 to 7 inches in height.
Included among the pocket notebooks is a set of six journals kept by Charles P.
Mott between March 1880 and March 1881 to record daily activities at the Menlo
Park Laboratory. The other eight pocket notebooks were used primarily by Edison.
The entries relate to a wide variety of topics, including electric lighting,
telephony, telegraphy, the phonograph, and hearing aids.

(6) Technical Scrapbooks, 1881-1888. These seven disbound scrapbooks
contain notes and drawings by Edison, which he subsequently gave to his attorneys
and draftsmen to work into patent applications. Most of the material concerns
electric lighting but there are also entries relating to telephony, telegraphy,
electric railways, and other topics.

(7) Unbound Notes and Drawings, 1879-1886. This set of technical notes and
drawings relates primarily to electric lighting. Other topics include telephony,
telegraphy, and electric railways. The documents appear on the microfilm in
chronological order.

(8) Oversize Notes and Drawings, 1879-1886. This is a set of technical
documents, primarily drawings, that are too large to fit in standard-size document
folders. Most of the material relates to electric lighting. A few drawings concern
telephones and electric railways. The documents appear on the microfilm in
chronological order, but many of them are undated. Included also among the
oversize notes and drawings is a separate set of Menlo Park machine shop drawings,
dating from 1879 and 1880. These drawings were produced by the staff of the
laboratory's machine shop prior to the production of experimental devices and
models. Almost al! of the drawings relate to work on the electric light, but there
area few miscellaneous drawings of the telephone.

(9) Undated Notes and Drawings. These technical documents relate
primarily to electric lighting. Other topics include telephony, telegraphy, and
electric railways. The notes and drawings appear on the microfilm in the
following order: (a) Menlo Park period, 1879-1881; (b) New York period, 1882-1886;
(c) drafts of caveats and patent applications.

Laboratory notebooks and other technical notes and drawings can also be
found in the Charles Batchelor and Francis R. Upton collections (Special
Collections Series).

Numbering Systems for Edison's Notebooks

Over the years a variety of different numbering systems have been employed by
Edison and others to identify the notebooks used at Menlo Park and the later laboratories.
Affixed onto the front cover of most of the standard-size Menlo Park notebooks is a label
containing the inscription: "From the Laboratory of T. A. Edison. Menlo Park, N. J. No.

-" The numbers themselves run from 1 through 249 and were probably assigned to
the books before they were put into use. The numbered books do not progress in strict
chronological order, and related books sometimes contain widely separated Menlo Park
numbers. About seventy of the numbered notebooks are missing from the collection at
the Edison National Historic Site. There are also a few notebooks whose damaged labels
obscure any numbers that may once have been affixed to them. This is the only
numbering system that was consistently in use during the time the books were being used
in the laboratory and, for this reason, the books are organized on the microfilm in the
order of their Menlo Park number.

Many of the Menlo Park notebooks also contain a second numbered label affixed
onto the front cover several inches above the Menlo Park label. These labels were
probably added to the books during the 1890s at the time they were sent to the General
Electric Board of Patent Control in New York City. With only a few exceptions, all of the
books containing the second numbered label also have the Board of Patent Control's
bookplate pasted onto their inside front covers.

For the first thirty-four Menlo Park notebooks, the two sets of numbers are
identical. Thereafter, the second set of numbers progress in the same sequence asthe
Menlo Park numbers, but many of the notebooks lack the second number and the General
Electric bookplate. Menlo Park Notebook #249, the last numbered book in the series, also
has a second label bearing the number 147. Similar labels appear on a few other
notebooks. Two of the New York notebooks are numbered 148 and 149. The six pocket
notebooks used by Charles P. Mott are numbered 150-155, and one other pocket notebook
is numbered 156.

Unlike the Menlo Park notebooks, the notebooks used at the laboratories in New
York, Fort Myers, and the Harrison lamp factory do not contain a standard printed label
or a standard notebook number. Some of these books, however, do have a smali numbered
label affixed to their spines. The numbers range from 23 to 35. Many of the Menio Park
notebooks lacking the General Electric bookplate contain similar labels, with numbers
ranging from 2 to 22. These numbers were probably affixed to the books after Edison's
move to West Orange in 1887. Over 100 books with these small numbered labels are found
among the West Orange notebooks. Book 1 and Book 36 both date from 1887.

Beginning in the late 1930s, the archivists at the West Orange Laboratory began
assigning "N-numbers" to the standard-size notebooks used by Edison at Menlo Park and
the later laboratories. A similar number with the prefix "PN" was assigned to each of the
pocket notebooks. This six-digit number corresponds to the first dated entry in the
notebook. For example, a notebook whose first dated entry was for November 9, 1878
would carry the number N-78-11-09. Unfortunately, this number is not always a reliable
indicator of the date when a book was first used. Many of the books were in use for a long
period of time before any entry was dated, and hundreds of other books contain no dated
entries. Moreover, subsequent research has revealed that many of the supplied or
conjectured dates are inaccurate. For these reasons, the N- or PN- number should never
be used as the basis for dating a notebook.

The following is a list of all the standard-size notebooks and the various numbers
that have been assigned to them.

MENLO PARK NOTEBOOKS, 1878-1882

The Menlo Park Notebooks cover the period 1878 to 1882. Some of the books
also contain entries from 1883, 1884, and 1885.. These books are the principal
sources for documenting the invention and development of Edison's system of
electric lighting and power. They also contain much material on the telephone, as
well as scattered entries detailing work on electric railways, batteries, ore
separation, telegraphy, and various other technologies. The books generated during
the first year of work on the electric light are primarily by Edison, Charles
Batchelor, and Francis Upton. The names of other laboratory assistants frequently
appear as witnesses. As the staff of the laboratory expanded, many other
individuals began making entries in the notebooks.

The Menlo Park notebooks are numbered from | to 249. Approximately 70
books are missing from the set. Pasted onto the inside front cover of many of the
Menlo Park notebooks is a bookplate with the inscription: "Library of the Board of
Patent Control, 120 Broadway, New York. May 1, 1896." The words "General
Electric" have been crossed out and the following notation added in red ink: "From
Library 44 Broad St., N.Y.C." Many of these notebooks also contain labels tipped
into various pages, describing the experiments that follow. These labels often
enumerate patents relating to these entries or suggest that the entries were
"unimportant" for defending patent claims.

All of the extant notebooks have been filmed with the exception of a few
books that contain mathematical calculations without accompanying notes and
drawings or that relate to routine shipping transactions. The books appear on the
microfilm in the order of their Menlo Park number.

The following notebooks have not been filmed:

Notebook #75 [N-80-06-10] (1880)
Notebook #136 [N-80-08-11] (1880)
Notebook #142 [N-80-11-27] (1880)
Notebook #151 [N-80-06-01 ] (1880)

Notebook #161 [N-81-10-13] (1881-1882)
Unnumbered notebook, N-80-01-16 (1880)
Unnumbered notebook, N-81-04-02 (1881-1882)

Assigning Dates and Authors to Menlo Park Notebooks

Initially, it was the practice for members of the laboratory staff to sign and
date each notebook entry. However, as the press of work and the size of the staff
increased, Edison and his associates sometimes neglected to sign and date their
work. As a result, there are many notebooks containing only a few dated entries,
and some of the books are entirely undated. There are several methods of
assigning dates or date ranges to undated notebook entries. Sometimes two
members of the staff recorded the same set of experiments in separate notebooks.
In such cases, an undated set of notes in one book may be dated in the other book.
Date ranges can be assigned to other undated entries by a careful examination of
dated entries on the pages preceding and following the undated entry. Moreover, it
is usually possible to determine the earliest date that a particular notebook could
have been used by examining the cover of the book. The earliest Menlo Park
notebooks (November 1878-April 1879) all have blue-green covers. The covers of
the later notebooks are a variety of colors, including dark red, light blue and
black, dark blue and black, and green-orange. An analysis of the notebooks with
dated entries reveals that books with similar covers were usually generated during
the same time period. Thus, it is possible to conjecture that an undated notebook
with a light blue-black cover dates from the period April-December 1880 and that
a notebook with a dark blue-black cover dates from the period after January 1881.

One other source is invaluable for dating notebook entries from 1880. There
are two Menlo Park Notebooks and six pocket notebooks that were used by Charles
P. Mott, a member of the Menlo Park office staff, to record the daily activities of
the laboratory between March 1880 and March 1881. Mott sometimes included
references to specific notebooks and mentioned the names of individuals working
on specific projects, thus allowing the attribution of authors and dates to entries
that could otherwise only be conjectured.

For the early books, which are primarily by Edison, Charles Batchelor, and
Francis Upton, it is usually possible for a careful researcher to distinguish writing
and drawing styles in cases where an entry is unsigned or more than one person
signed the entry. For the later books it is more difficult to attribute authorship,
but the Mott journals can help the researcher become familiar with the writing and
drawing styles of the various staff members.

A more extended discussions of these issues can be found in Robert Freidel
and Paul Israel, Edison's Electric Light: Biography of an Invention (New
Brunswick: Rutgers University Press, 1986), pp. 233-238.

Menlo Park Notebook #1 [N-78-11-28]

This notebook covers the period November 1878-July 1879. Most of the
entries are by Edison, Charles Batchelor, and Francis Upton. There are also entries
by George E. Carman and George Jackson. The names of Martin Force and John
Ott appear occasionally as witnesses. Almost all of the material relates to
experiments on electric lighting. Included are notes and drawings of lamps; notes
on materials for filaments; drawings of devices for producing and testing filaments;
notes, drawings, and calculations about generators; notes by Edison on gas use in
San Francisco; and drawings of arc lamps. There are also notes on batteries made
and tested, notes on carbon button tests, and notes and drawings of telephones.
The book contains 274 numbered pages.

Blank pages not filmed: 240-241, 258-261, 270-273.

Missing page numbers: 264-265, 268-269.

Menlo Park Notebook #2 [N-78-11-22]

This notebook covers the period November 1878-June 1879. Most of the
entries are by Charles Batchelor and Francis Upton. There are also entries by
Edison and John Kruesi. The name of Martin Force appears occasionally as a
witness. Almost all! of the material relates to experiments on electric lighting.
Included are notes and drawings of spiral filaments; tests of filaments brought to
incandescence with batteries and generators; notes, drawings, and calculations
about generators; drawings of a MacCleod gauge; and notes by Edison on another
inventor's arc light patent. There are also drawings of the telephone, notes on
chalk and carbon buttons, and a memorandum by Edison on Frank McLaughlin's
prospecting trip to the Chandiere River in Canada. The book contains 262
numbered pages.

Blank pages not filmed: 48-49, [12-115, 118-13], 136-137, 158-201, 206-224,
227, 230-262.

Missing page numbers: 225-226.

Menlo Park Notebook #4 [ N-78-12-04.2]

This notebook covers the period December 1878-April 1879. Most of the
entries are by Edison, Charles Batchelor, and Francis Upton. There are also entries
by John Kruesi, John Ott, and George Jackson. Almost ali of the material relates
to experiments on electric lighting. There are drawings of lamps, including vacuum
experiments; drawings of a machine for insulating spiral filaments; and notes,
drawings, and calculations about generators, with a series of numbered experiments ©
cross-referenced to other notebooks. There are also notes by Upton taken from a
work by John Tyndall on heat; drawings of telephones; drawings of a blowpipe and
of a microscope table; Kruesi's notes on work done to the laboratory buildings; and
a memorandum by Edison on scrapbook titles. The book contains 282 numbered
pages followed by one unnumbered page.

Blank pages not filmed: 114-115, 164-165, 220-245, 248-279.

Missing page numbers: 143-144, 161-162.

Menlo Park Notebook #7 [N-78-12-11]

This notebook covers the period December 1878-April 1879. The entries are
by Edison, Charles Batchelor, and Francis Upton. Almost all of the material
relates to experiments on electric lighting. Included are drawings of lamps; notes
on filaments; drawings of generators, including one labeled "Edison Ist drawing";
comparisons to gas lighting costs; and calculations for an electric lighting system.
There are also notes on chalks for telephones and a drawing of a Gramme machine
combined with an induction coil for the telephone. The book contains 282
numbered pages and one unnumbered page.

Blank pages not filmed: 1, 76-77, 226-227, 246-275.

Missing page numbers: 233-234.

Menlo Park Notebook #8 [N-78-12-20.2]

This notebook covers the period December 1878-June 1879. Most of the
entries are by Francis Upton. There are also entries by Edison, Charles Batchelor,
John Kruesi, and George Jackson. All of the material relates to experiments on
electric lighting. There are notes and calculations by Upton about meters, a series
of tests by Upton on generators, and Upton's calculations for an electric lighting
system. Other material includes a test machine for driving magnetos, designed by
Batchelor and built by Jackson; notes by Edison on hand turning a generator; and
drawings by Krusei showing the layout of pipes in one of the laboratory buildings.
The label on the front cover is marked "Faradic machines No. 1" and "Electro
deposition Tests." The book contains 284 numbered pages.

Blank pages not filmed: 76-77.

Menlo Park Notebook #9 [N-78-12-15.1]

This notebook covers the period December 1878-March 1879. All of the
entries are by Edison, Charles Batchelor, and Francis Upton, with the exception of
a few drawings by John Kruesi. The name of John Ott occasionally appears as a
witness. Most of the material relates to experiments on electric lighting. There
are drawings of lamps, including vacuum experiments; drawings of devices for
making and testing wire spiral filaments; notes on platinum and platinum-iridium
wire; notes and drawings of generators; calculations of system costs, including
comparisons to gas lighting costs; and drawings and calculations about meters,
including some labeled "Sprague's Exhibit Edison's Early Sketch No. [2-4] Jan. 12th
1886." There are also drawings of the electric pen and the phonograph. The book
contains 241 numbered pages followed by 30 unnumbered pages.

Menlo Park Notebook #10 [N-78-12-16]

This notebook covers the period December 1878-January 1879. Most of the
entries are by Francis Upton. There are also entries by Edison and Charles
Batchelor. Some entries have been signed by Edison. Almost all of the material
relates to experiments on electric lighting. Included are calculations by Upton
about generators and electric distribution systems, with a few calculations by
Edison; notes and drawings of lamps; and notes and drawings of generators. There
are also notes by Upton on miscellaneous subjects, from etheric force, electricity,
magnetism, and phosphorescence to light and heat. Similar notes can be found in
Menlo Park Notebook #15. The book contains 282 numbered pages.

Blank pages not filmed: 88-89, 198-201, 280-281.
